26 Mechanical Connections Liquid Refrigerant Piping The equipment must be connected to an RDU. Ceiling-suspended refrigerant piping should be present. Make connections to the InRow RA cooling modules using the refrigerant distribution unit (RDU), piping kits, and flexible hoses. See the RDU Installation manual for more information. Calculate an equivalent length based on the actual linear length of the run, including valves and fittings. Isolate piping from structural surfaces using vibration clamps. Piping requirements Install all refrigerant lines in accordance with applicable industry guidelines as well as local and national codes and regulations. The maximum equivalent length for refrigerant piping between the RDU and the most distant cooling module is 24.4 m (80 ft). Use the table below to calculate the equivalent length of fittings to ensure that maximum equivalent length is not exceeded. Connection lines between the distribution piping and cooling module are 3/4 in nominal (7/8 in ACR tubing size) for the refrigerant supply and 1 in nominal (1-1/8 in ACR tubing size) for the refrigerant return. Field fabricated connections between the cooling module and distribution piping may be a maximum of 3.05 m (10 ft) equivalent length. This equivalent length must be included in total equivalent length between the cooling module and RDU. Note: 1. If flex hose is used, the total equivalent length is reduced to 19.8 m (65 ft), NOT including the flex hose lengths. Ensure your installation conforms to these requirements by calculating the equivalent length based on the actual linear length of the run, plus the equivalent length of valves and fittings. Note: 2. All fittings should be long-radius to minimize pressure drop. Note: 3. Install all piping in accordance with applicable industry guidelines as well as local and national codes and regulations.
